The aim of this work is to develop an automatic shape optimization procedure where simulations are run on a computer cluster. The user input is limited and the optimization is made automatic by connecting three commercial codes in a closed optimization loop, i.e. AVL Fire (mesh generation and CFD calculations), modeFRONTIER (optimization, process automation and post-processing) and Sculptor (mesh deformation).

Due to various difficulties in performing the classic aerodynamic optimization, a new RSM-based approach (Adaptive Multi-Stage Response Surface Modeling) has been developed, resulting in lower CFD calculation costs, more accurate response surfaces and sampling robustness

This presentation explain how to set up a morphological shape optimization project by integrating Converge CFD and Sculptor with modeFRONTIER This procedure simplifies the entire routine and productivity increases 5 times thanks to the automation of tasks. By quickly parametrizing complex models and controlling the whole process just from the interface of modeFRONTIER, designers avoid to build the initial mesh and have no need to “re-CAD” or “re-mesh

This Webinar, hosted jointly by ESTECO and Optimal Solutions, provides a demonstration of the new interface between the modeFRONTIER and Sculptor, including some relevant case studies where the direct coupling has been used.

Users of ESTECO’s process integration and optimization software modeFRONTIER and Optimal Solutions’ SCULPTOR mesh morphing software will now find it even easier to couple the two tools, thanks to the new interface.

In the past few decades, a number of environmentally friendly technologies in the automotive industry have been developed. Automotive styling is also regarded as an important factor in resolving environmental issues by reducing drag force, which results in high fuel efficiency. This paper demonstrates an efficient automotive aerodynamic optimization process and automatic system based on CFD.

Competitiveness drives companies to engineer and produce power-train components and systems that over time are higher in product performance, more fuel efficient, less polluting while responding to the increased complexity of design and mechanical operations and requirements.
